Last year we announced our smart contract oracle that we dubbed “Snopes Meets Mechanical Turk on a Blockchain”. Today we’re excited to tell you about the mainnet release of this project, now called Realitio. Realitio is a crowd-based oracle which relies on a system of escalating bonds to generate correct…

Last year we announced our on-chain smart contract oracle system, Reality Check, which we described as Snopes meets mechanical Turk on a blockchain. We’ve completed our audit and we’re announcing a bug bounty for the smart contracts and documentation, as of commit 19d72f85f821c3e27400fc0f3514b9bddb64ae59. It covers the following contracts: RealityCheck.sol Arbitrator.sol …

We are now live on mainnet at reality.eth. When we started building the Reality Keys smart contract oracle in 2013, we assumed that most of the data people would want would be able to be pulled from existing data feed APIs. But in practice we found that a lot of…

Tech people love cool new things, and when we talk about Ethereum we hardly ever talk about it as a way of doing things Bitcoin could already do. But the experience of using Bitcoin to pay for things is getting increasingly painful, and it’s time has come to look at…

It’s easy to create a token on the Ethereum network. Forking one is also, in theory, a simple business. A token typically consists of a database of balances, some code showing how to access it and, potentially, some other code that does other stuff. You simply make your new contract…

Dumb smart contracts There has long been a school of thought that says that smart contracts are mostly pointless. Most interesting contracts depend on some outside event happening in the real world: A stock price going up or down, an election being won or lost, an earthquake in Tokyo happening or not happening, …
